When the display apparatus 20 is in the standby mode, the first processor 261 maintains a power-saving state, in other words, a turned-off state. Here, the turned-off state refers to a kind of soft turned-off state in which power supplied to the display apparatus 20 is not completely shut off. When the display apparatus 20 in the standby mode receives a user input through the user input receiver 270 to be described later or receives a signal from the electronic apparatus 10, the second processor 262 detects such reception and wakes up the first processor 261. The first processor 261 is switched over from the turned-off state to a turned-on state, and it is thus possible to identify a mode change of the display apparatus 20, i.e. from the turned-off state of the standby mode to the turned-on state of a normal mode.

According to an embodiment, the voice recognition function of the voice recognition module 263 may be performed based on one or more voice recognition algorithms. For example, the voice recognition module 263 extracts a vector of voice features from a user voice, and compares the extracted vector with the acoustic model of the database 251, thereby performing the voice recognition. Here, the acoustic model may for example be a model based on previously performed learning.

An embedded type of the voice recognition module 263 resident in the CPU provided as the processor 260 is described by way of example, but the disclosure is not limited to this example. Alternatively, the voice recognition module 263 may be embodied by an element of the display apparatus 20 separated from the CPU, for example, by a microcomputer (MICOM) or the like separate chip as a dedicated processor for the voice recognition function.

According to an embodiment, the processor 260 may receive information about a user voice from the electronic apparatus 10 provided as the external apparatus through the communicator 240 based on the identified change in the display apparatus 20 from the turned-off state (i.e. the standby mode) to the turned-on state (i.e. the normal mode), process the user voice, and control the display 230 to display an image based on a process result.

According to an embodiment, the user input receiver 270 may further include a microphone to receive a voice uttered by a user/the sound, in other words, a user voice, and the microphone may be provided in the main body of the display apparatus 20, the remote controller, etc.

Below, embodiments that the user voice is processed in the electronic apparatus or the display apparatus according to the disclosure will be described with reference to the accompanying drawings.

FIGS. 5 and 6 conceptually illustrate operation between an electronic apparatus and a display apparatus according to a first embodiment of the disclosure, FIG. 7 is a flowchart showing a method of controlling the electronic apparatus according to the first embodiment of the disclosure, FIG. 8 illustrates an example that the electronic apparatus according to the first embodiment of the disclosure processes a user voice, and FIG. 9 illustrates an example that the display apparatus according to the first embodiment of the disclosure processes a user voice.

The electronic apparatus 10 according to the first embodiment of the disclosure may, as shown in FIGS. 5 and 6, identify the power state of the display apparatus 20, i.e. whether the display apparatus 20 is in the turned-on state or the turned-off state, based on the user voice received through the microphone 120, and operate in a TV-off mode or a TV-on mode based on the identification result.

The electronic apparatus 10 may operate in the TV-off mode (or an exclusive use mode) as shown in FIG. 5 based on the identified turned-off state of the display apparatus 20, thereby processing the received user voice and outputting a process result as a sound through the speaker 110.

The electronic apparatus 10 may operate in the TV-on mode (or a TV link mode) as shown in FIG. 6 based on the identified turned-on state of the display apparatus 20, thereby transmitting the information about the received user voice to the display apparatus 20 through the communicator 140, and making a request for processing the voice to the display apparatus 20. The display apparatus 20 processes the user voice, and outputs a process result as an image through the display 230.

Specifically, as shown in FIG. 7, the electronic apparatus 10 may receive a user voice uttered by a user through the microphone 120 (401). The electronic apparatus 10 may receive various unrestricted user voices through the microphone 120, and may for example, as shown in FIG. 8, receive a voice corresponding to a searching request.

According to an embodiment, the processor 160 may detect a predetermined keyword uttered by a user (hereinafter, referred to as a wake-up keyword), for example, “Hi, Bixby” as shown in FIG. 8, thereby identifying that the user voice is received through the microphone 120. One or more wake-up keywords may be previously set by the manufacturer of the electronic apparatus 10, a service provider, etc. or may be set by a user.

Here, when it is identified that a predetermined keyword is input as the user voice through the microphone 120, the processor 160 may execute or activate the AI speaker application installed in the electronic apparatus 10. For example, when it is identified that “Hi, Bixby” or the like wake-up keyword is input, the processor 160 may switch the running state of the AI speaker application over from the background mode to the foreground mode.

Based on the user voice received in the operation 401, the processor 160 identifies the state of the external apparatus, i.e. the display apparatus 20 through the communicator 140 (402). For example, the processor 160 transmits a preset signal to the display apparatus 20 through the communicator 140, and identify the power state of the display apparatus 20, in other words, whether the display apparatus 20 is in the turned-on or turned-off state, according to whether a response signal to the preset signal is received from the display apparatus 20.

Based on the identification in the operation 402, it may be identified that the display apparatus 20 is in the turned-on state or the turned-off state (403).

When it is identified in the operation 403 that the display apparatus 20 is in the turned-off state, the processor 160 may process the user voice received in the operation 401 (404).

Specifically, the electronic apparatus 10 may operate in the TV-off mode, so that the processor 160 can apply the voice recognition to the user voice and process the user voce to thereby perform an operation based on a result of the voice recognition.

The processor 160 may control the signal processor 130 to convert the user voice, i.e. a sound wave received through the microphone 120 into an electric signal.

According to an embodiment, the voice recognition module 161 of the processor 160 may perform the voice recognition by extracting a vector of voice features from a signal of a converted user voice, and comparing the extracted vector with the acoustic model of the server 30 or the database 151.

The processor 160 performs operations to process the user voice based on the foregoing voice recognition, and output the process result.

For example, as shown in FIG. 8, when the user voice is related to a request for searching for local restaurants, the processor 160 may perform searching through the communicator 140, and control the signal processor 130 to generate an audio feedback, i.e. a response voice based on the process result (i.e. a searching result).

The processor 160 may output a sound corresponding to the process result of the operation 404 through the speaker 110 (405). For example, when the user voice processed in the operation 404 is related to a request for searching for local restaurants, a sound based on the searching result is output through the speaker 110 as shown in FIG. 8. This sound corresponds to the response voice generated in the operation 404.

Meanwhile, when it is identified in the operation 403 that the display apparatus 20 is in the turned-on state, the processor 160 may transmit information about the user voice received in the operation 401 to the display apparatus 20 and makes a request for processing the voice to the display apparatus 20 (406).

Here, the electronic apparatus 10 operates in the TV-on mode, so that the processor 160 can control the signal processor 130 to convert the user voice, i.e. a soundwave received through the microphone 120 into an electric signal, and transmit data about the converted signal as the information about the user voice to the display apparatus 20 through the communicator 140.

The processor 260 of the display apparatus 20 may apply the voice recognition to the user voice, and process the user voice to thereby perform an operation based on a result of the voice recognition. Here, when the information about the user voice is received from the electronic apparatus 10, the processor 260 may execute or activate the AI speaker application installed in the display apparatus 20, in which the activation include switching over the running state of the AI speaker application from the background mode to the foreground mode.

According to an embodiment, the voice recognition module 263 of the processor 260 extracts a vector of voice features from information about the received user voice, and compares the extracted vector with the acoustic model of the database 251 or the server 30, thereby performing the voice recognition.

The processor 260 of the display apparatus 20 performs operations to process the user voice based on the voice recognition as described above, and output the process result.

For example, as shown in FIG. 9, when the user voice is related to a request for searching for local restaurants, the processor 260 may perform searching through the communicator 240, and control the display 230 to display a UI 501 showing the search result. Here, a plurality of items 502 selectable by a user may be listed in the UI 501 showing the search result. When a user selects one item 502 in the list, the processor 260 may control the display 230 to display additional information about the selected item, for example, a map, contact information, user reviews, etc., thereby allowing the user to further obtain various pieces of information.

FIG. 9 shows an example that the request for searching for restaurants or the like is received as the user voice and the searching results are displayed, but there are no limits to a target to be processed or searched based on the user voice according to the disclosure. For example, various user voices related to a TV service such as TV channel searching, program/content searching, etc. may be processed.

Further, the processor 260 may output a signal corresponding to the process result (or the searching result) to the electronic apparatus 10 through the communicator 240.

The processor 160 of the electronic apparatus 10 may receive the process result of the operation 406 from the display apparatus 20, and output a corresponding sound through the speaker 110 (407). For example, when the process for the user voice in the operation 406 includes searching for local restaurants or the like, the searching result may be not only displayed on the display apparatus 20 but also output as a sound corresponding to the audio feedback, i.e. the response voice through the speaker 110 as shown in FIG. 9.

According to the first embodiment of the disclosure, the electronic apparatus 10 autonomously processes the user voice or allows the external apparatus, i.e. the display apparatus 20 to selectively process the user voice according to whether the external apparatus, i.e. the display apparatus 20 with which the electronic apparatus 10 can communicate is in the turned-off state or the turned-on state. Therefore, as compared with the case where only the audio feedback is given through the electronic apparatus 10, the visual feedback is further provided through the screen of the display apparatus 20, thereby improving a user's accessibility to the process result, and increasing convenience as additional information is more easily obtained as necessary.

FIG. 10 conceptually illustrates operation between an electronic apparatus and a display apparatus according to a second embodiment of the disclosure, and FIG. 11 is a flowchart showing a method of controlling the electronic apparatus according to the second embodiment of the disclosure.

The electronic apparatus 10 according to the second embodiment of the disclosure may, as shown in FIG. 10, identify the power state of the display apparatus 20, i.e. whether the display apparatus 20 is in the turned-on state or the turned-off state, based on the user voice received through the microphone 120, and transmit a request for turning on the display apparatus 20 when it is identified that the display apparatus 20 is in the turned-off mode.

Here, the electronic apparatus 10 may output a sound for guiding a user to turn on the display apparatus 20 of the turned-on state through the speaker 110, and the display apparatus 20 may be switched over from the turned-off state to the turned-on state in response to the request from the electronic apparatus 10.

The electronic apparatus 10 operates in the TV-on mode (or the TV link mode) as shown in FIG. 10 based on the switching of the display apparatus 20 from the turned-off state to the turned-on state. The electronic apparatus 10 operates in the TV-on mode, thereby transmitting the information about the received user voice to the display apparatus 20 through the communicator 140, and making a request for processing the voice to the display apparatus 20. The display apparatus 20 processes the user voice, and outputs a process result as an image through the display 230.

Specifically, as shown in FIG. 11, the electronic apparatus 10 may receive a user voice uttered by a user through the microphone 120 (601). Here, the electronic apparatus 10 may receive various unrestricted user voices through the microphone 120.

According to an embodiment, the processor 160 may detect a predetermined keyword uttered by a user (i.e. the wake-up keyword), thereby identifying that the user voice is received through the microphone 120.

When it is identified that a predetermined keyword is input as the user voice through the microphone 120, the processor 160 may execute or activate the AI speaker application installed in the electronic apparatus 10, in which the activation includes switching over the running state of the AI speaker application from the background mode to the foreground mode.

Based on the user voice received in the operation 601, the processor 160 identifies the state of the external apparatus, i.e. the display apparatus 20 through the communicator 140 (602). For example, the processor 160 transmits a preset signal to the display apparatus 20 through the communicator 140, and identify the power state of the display apparatus 20, in other words, whether the display apparatus 20 is in the turned-on or turned-off state, according to whether a response signal to the preset signal is received from the display apparatus 20.

Based on the identification in the operation 602, it may be identified that the display apparatus 20 is in the turned-on state or the turned-off state (603).

When it is identified in the operation 603 that the display apparatus 20 is in the turned-off state, the processor 160 according to an embodiment may output a sound for guiding a user to turn on the display apparatus 20 through the speaker 110 (604). According to the disclosure, there are no limits to the guide sound to be output, and the guide sound may for example include content for guiding a user to press a specific button of the electronic apparatus 10 so that a turning-on request can be transmitted to the display apparatus 20, or content for guiding a user to turn on the display apparatus 20.

Alternatively, the operation 604 of outputting the guide sound may be omitted in the electronic apparatus 10.

When it is identified in the operation 603 that the display apparatus 20 is in the turned-off state, the processor 160 may control the communicator 140 to transmit a request signal for turning on the display apparatus 20 to the display apparatus 20 (605).

According to an embodiment, when a user presses the specific button in response to the output of the guide sound for the press of the corresponding button in the operation 604, the processor 160 may for example transmit a request signal for turning on the display apparatus 20 through the communicator 140.

According to another embodiment, when it is identified that the display apparatus 20 is in the turned-off state, the processor 160 may directly transmit the request signal for turning on the display apparatus 20 through the communicator 140 without the output of the guide sound in the operation 604 or a user's control.

The turning-on request signal in the operation 605 is received in the display apparatus 20, so that the display apparatus 20 can be switched over from the turned-off state to the turned-on state in response to the reception. The processor 260 of the display apparatus 20 may control the communicator 250 to transmit a signal for informing that the display apparatus 20 is turned on to the electronic apparatus 10, and therefore a feedback signal to the turning-on request is transmitted to the electronic apparatus 10.

When it is identified in the operation 603 that the display apparatus 20 is in the turned-on state, the processor 160 may transmit information about the user voice received in the operation 601 to the display apparatus 20 and makes a request for processing the voice to the display apparatus 20 (606). The processor 160 may identify that the display apparatus 20 is in the turned-on state, based on the response signal from the display apparatus 20. According to an embodiment, the response signal may correspond to the feedback signal to the foregoing turning-on request.

Here, the electronic apparatus 10 operates in the TV-on mode, so that the processor 160 can control the signal processor 130 to convert the user voice, i.e. a soundwave received through the microphone 120 in the operation 601 into an electric signal, and transmit data about the converted signal as the information about the user voice to the display apparatus 20 through the communicator 140.

The processor 260 of the display apparatus 20 may apply the voice recognition to the user voice, and process the user voice to thereby perform an operation based on a result of the voice recognition. Here, when the information about the user voice is received from the electronic apparatus 10, the processor 260 may execute or activate the AI speaker application installed in the display apparatus 20, in which the activation include switching over the running state of the AI speaker application from the background mode to the foreground mode.

According to an embodiment, the voice recognition module 263 of the processor 260 extracts a vector of voice features from information about the received user voice, and compares the extracted vector with the acoustic model of the database 251 or the server 30, thereby performing the voice recognition.

The processor 260 of the display apparatus 20 processes the user voice based on the voice recognition as described above, and display the process result on the display 230 as shown in FIG. 9. Further, the processor 260 may output a signal corresponding to the process result (i.e. the search result) to the electronic apparatus 10 through the communicator 140.

The processor 160 of the electronic apparatus 10 may receive the process result of the operation 606 from the display apparatus 20, and output a corresponding sound through the speaker 110 (607). Thus, the result of processing the user voice in the operation 606 may be not only displayed on the display apparatus 20 but also output as a sound corresponding to the audio feedback, i.e. the response voice through the speaker 110.

According to the second embodiment of the disclosure, when the external apparatus, i.e. the display apparatus 20 with which the electronic apparatus 10 can communicate is in the turned-off state, the electronic apparatus 10 controls the external apparatus, i.e. the display apparatus 20 to be turned on to process the user voice. Therefore, as compared with the case where only the audio feedback is given through the electronic apparatus 10, the visual feedback is further provided through the screen of the display apparatus 20, thereby improving a user's accessibility to the process result, and increasing convenience as additional information is more easily obtained as necessary.

FIG. 12 conceptually illustrates operation between an electronic apparatus and a display apparatus according to a third embodiment of the disclosure, and FIG. 13 is a flowchart showing a method of controlling the electronic apparatus according to the third embodiment of the disclosure.

The electronic apparatus 10 according to the third embodiment of the disclosure may, as shown in FIG. 12, identify a service type (or a content type) related to a user voice, based on the user voice received through the microphone 120, and autonomously processes the user voice or requests the display apparatus 20 to process the user voice based on the identification result.

For example, when it is identified that the received user voice is related to services of providing acoustic content, i.e. audio/sound, for example, music play, a weather report, current time, a timer, etc., the electronic apparatus 10 may autonomously process the corresponding voice.

In this case, the electronic apparatus 10 operates in the TV-off mode, thereby autonomously processing the user voice and outputting the process result through the speaker 110.

On the other hand, when it is identified that the received user voice is related to services of providing visual content, i.e. video/image, for example a movie, a TV program, etc., the electronic apparatus 10 may request the display apparatus 20 to process the corresponding voice.

In this case, the electronic apparatus 10 may transmits a request signal for processing the voice to the display apparatus 20, and thus operates in the TV-on mode (i.e. the TV link mode) as shown in FIG. 12. The electronic apparatus 10 operates in the TV-on mode, thereby transmitting the information about the received user voice to the display apparatus 20 through the communicator 140, and making a request for processing the voice to the display apparatus 20. The display apparatus 20 processes the user voice, and outputs a process result as an image through the display 230.

Specifically, as shown in FIG. 13, the electronic apparatus 10 may receive a user voice uttered by a user through the microphone 120 (701). Here, the electronic apparatus 10 may receive various unrestricted user voices through the microphone 120.

According to an embodiment, the processor 160 may detect a predetermined keyword uttered by a user (i.e. the wake-up keyword), thereby identifying that the user voice is received through the microphone 120.

When it is identified that a predetermined keyword is input as the user voice through the microphone 120, the processor 160 may execute or activate the AI speaker application installed in the electronic apparatus 10, in which the activation includes switching the running state of the AI speaker application over from the background mode to the foreground mode.

Based on the user voice received in the operation 701, the processor 160 identifies the service type of the received user voice (702). For example, the processor 160 identifies whether the user voice is related to the service of visual content such as a movie, a TV program, etc. or acoustic content such as music, weather, time, a timer, etc.

Based on the identification of the operation 702, the service type of the user voice is identified as the service of the visual content or the service of the acoustic content (703).

When it is identified in the operation 703 that the service type of the user voice is related to the visual content, the processor 160 may identify whether the display apparatus 20 is in the turned-off state or the turned-on state (704). For example, the processor 160 transmits a preset signal to the display apparatus 20 through the communicator 140, and identify the power state of the display apparatus 20, in other words, whether the display apparatus 20 is in the turned-on or turned-off state, according to whether a response signal to the preset signal is received from the display apparatus 20.

When it is identified in the operation 704 that the display apparatus 20 is in the turned-off state, the processor 160 may output a sound for guiding a user to turn on the display apparatus 20 through the speaker 110 (705). According to the disclosure, there are no limits to the guide sound to be output, and the guide sound may for example include content for guiding a user to press a specific button so that turning-on request can be transmitted to the display apparatus 20 of the electronic apparatus 10.

Alternatively, the operation 705 of outputting the guide sound may be omitted in the electronic apparatus 10.

When it is identified in the operation 704 that the display apparatus 20 is in the turned-off state, the processor 160 may control the communicator 140 to transmit a request signal for turning on the display apparatus 20 to the display apparatus 20 (706).

According to an embodiment, when a user presses the specific button in response to the output of the guide sound for the press of the corresponding button in the operation 705, the processor 160 may for example transmit a request signal for turning on the display apparatus 20 through the communicator 140.

According to another embodiment, when it is identified that the display apparatus 20 is in the turned-off state, the processor 160 may directly transmit the request signal for turning on the display apparatus 20 through the communicator 140 without the output of the guide sound in the operation 705 or a user's control.

The turning-on request signal in the operation 706 is received in the display apparatus 20, so that the display apparatus 20 can be switched over from the turned-off state to the turned-on state in response to the reception. The processor 260 of the display apparatus 20 may control the communicator 250 to transmit a signal for informing that the display apparatus 20 is turned on to the electronic apparatus 10, and therefore a feedback signal to the turning-on request is transmitted to the electronic apparatus 10.

When it is identified in the operation 704 that the display apparatus 20 is in the turned-on state, the processor 160 may transmit information about the user voice received in the operation 701 to the display apparatus 20 and makes a request for processing the voice to the display apparatus 20 (707). The processor 160 may identify that the display apparatus 20 is in the turned-on state, based on the response signal from the display apparatus 20. According to an embodiment, the response signal may correspond to the feedback signal to the foregoing turning-on request.

Here, the processor 160 operates in the TV-on mode, and thus controls the signal processor 130 to convert the user voice, i.e. a soundwave received through the microphone 120 in the operation 701 into an electric signal, and transmit data about the converted signal as the information about the user voice to the display apparatus 20 through the communicator 140.

The processor 260 of the display apparatus 20 may apply the voice recognition to the user voice, and process the user voice to thereby perform an operation based on a result of the voice recognition. Here, when the information about the user voice is received from the electronic apparatus 10, the processor 260 may execute or activate the AI speaker application installed in the display apparatus 20, in which the activation include switching over the running state of the AI speaker application from the background mode to the foreground mode.

According to an embodiment, the voice recognition module 263 of the processor 260 extracts a vector of voice features from information about the received user voice, and compares the extracted vector with the acoustic model of the database 251 or the server 30, thereby performing the voice recognition.

The processor 260 of the display apparatus 20 processes the user voice based on the voice recognition as described above, and display the process result, for example, on the display 230 as shown in FIG. 9. Further, the processor 260 may output a signal corresponding to the process result (i.e. the search result) to the electronic apparatus 10 through the communicator 140.

The processor 160 of the electronic apparatus 10 may receive the process result of the operation 707 from the display apparatus 20, and output a corresponding sound through the speaker 110 (708). Thus, the result of processing the user voice in the operation 707 may be not only displayed on the display apparatus 20 but also output as a sound corresponding to the audio feedback, i.e. the response voice through the speaker 110.

Meanwhile, when it is identified in the operation 703 that the service type of the user voice is related to the acoustic content, the processor 160 may process the user voice received in the operation 701 (709).

Specifically, the electronic apparatus 10 operates in the TV-off mode, and thus the processor 160 applies the voice recognition to the user voice, and performs a process related to the user voice so that an operation based on the result of the voice recognition can be performed.

The processor 160 may control the signal processor 130 to convert the user voice, i.e. the sound wave received through the microphone 120 into an electric signal.

According to an embodiment, the voice recognition module 161 of the processor 160 extracts a vector of voice features from the signal converted from the user voice, and compares the extracted vector with the acoustic model of the server 30 or the database 151, thereby performing the voice recognition.

The processor 160 performs operations to process the user voice based on the foregoing voice recognition, and output the process result.

For example, when the user voice is related to a request for playing a certain genre, for example, classic music, the processor 160 may search for music of the corresponding genre through the communicator 140.

The processor 160 may output a sound corresponding to the process result of the operation 709 through the speaker 110 (710). For example, when the user voice processed in the operation 709 is identified as a request for playing classic music, the speaker 110 may be controlled to output a sound, i.e. play music based on the process result (i.e. the searching result).

According to the third embodiment of the disclosure as described above, the electronic apparatus 10 can process the user voice through the display apparatus 20 when the service type of the user voice is related to the visual content. Therefore, it is more convenient for a user because the user can more efficiently receive a service, i.e. content through the screen of the display apparatus 20.

FIG. 14 conceptually illustrates operation between an electronic apparatus and a display apparatus according to a fourth embodiment of the disclosure, and FIG. 15 is a flowchart showing a method of controlling the electronic apparatus according to the fourth embodiment of the disclosure.

The display apparatus 20 according to the fourth embodiment of the disclosure may, as shown in FIG. 14, identify a connection state between the electronic apparatus 10 and the display apparatus 20, i.e. whether or not the display apparatus 20 and the electronic apparatus 10 are connected for the wired or wireless communication, based on change of the display apparatus 20 from the turned-off state to the turned-on state, and receive a request for processing the user voice from the electronic apparatus 10 when it is identified that the display apparatus 20 and the electronic apparatus 10 are connected.

Here, when it is identified that the display apparatus 20 and the electronic apparatus 10 are not connected, the display apparatus 20 performs connection settings for the communication with the electronic apparatus 10, and then receive the request for processing the voice from the connected electronic apparatus 10.

The electronic apparatus 10 operates in the TV-on mode, thereby transmitting the information about the user voice to the display apparatus 20, and making a request for processing the voice to the display apparatus 20. The display apparatus 20 may, as shown in FIG. 14, process the user voice, and output a process result as an image through the display 230.

Specifically, as shown in FIG. 15, the display apparatus 20 may be switched over from the turned-off state to the turned-on state (801).

Here, the turned-off state refers to a kind of soft turned-off state in which the display apparatus 20 operates in the standby mode of receiving the standby power. As the first processor 261 of the turned-off state is woken up by the second processor 262, the display apparatus 20 is switched over to the turned-on state, in other words, the normal mode.

According to an embodiment, when the first processor 261 is in the power-saving state, i.e. the turned-off state, the second processor 262 may identify whether a user input is received through the user input receiver 270, and identify the change of the display apparatus 20 from the turned-off state to the turned-on state based on the received user input according to identification results. Here, the received user input may for example be based on a user's control responding to the guide sound for turning on the display apparatus, which is output in the operation 604 according to the embodiment of FIG. 11.

According to another embodiment, when the first processor 261 is in the power-saving state, i.e. the turned-off state, the second processor 262 may identify that a request signal for turning on the display apparatus 20 is received from the electronic apparatus 10 through the communicator 240, and identify that the display apparatus 20 is switched over from the turned-off state to the turned-on state based on the received signal according to the identification results. Here, the received request signal may for example be based on a signal transmitted in the operation 605 according to the embodiment of FIG. 11.

When the display apparatus 20 is switched over to the turned-on state in the operation 801, the first processor 261 is woken up and identifies the connection state of the external apparatus, i.e. the electronic apparatus 10 through the communicator 140 (802). For example, the first processor 260 may transmit a preset signal to the electronic apparatus 10 through the communicator 140, and identify whether the display apparatus 20 and the electronic apparatus 10 are connected for the wired or wireless communication based on whether the response signal to the preset signal is received from the electronic apparatus 10.

Based on the identification in the operation 802, it is identified whether the display apparatus 20 and the electronic apparatus 10 are connected, in other words, whether they are in a connected state or a disconnected state (803).

When it is identified in the operation 803 that the display apparatus 20 is not connected to the electronic apparatus 10, the processor 260, i.e. the first processor 261 may perform settings for connection with the electronic apparatus 10 through the communicator 140 (804). Here, there are no limits to the type of communication connection between the display apparatus 20 and the electronic apparatus 10, and the type of communication connection may for example include Bluetooth, Wi-Fi or the like wireless communication connection.

When it is identified in the operation 803 that the display apparatus 20 is connected to the electronic apparatus 10, the processor 260, i.e. the first processor 261 may receive information about the input user voice from the electronic apparatus 10 through the speaker 110 (805). Here, the received information about the user voice may include a request for processing the voice, and may correspond to the information about the user voice transmitted from the electronic apparatus 10 to the display apparatus 20 in the operation 606 according to the embodiment of FIG. 11 or the operation 707 according to the embodiment of FIG. 13.

According to an embodiment, when the information about the user voice is received from the electronic apparatus 10, the processor 260 may execute or activate the AI speaker application installed in the display apparatus 20, in which the activation include switching over the running state of the AI speaker application from the background mode to the foreground mode.

Based on the information about the user voice received in the operation 804, the processor 260 may process the corresponding user voice (806).

Specifically, the processor 260 may apply the voice recognition to the user voice, and process the user voice to perform an operation based on a result of the voice recognition.

According to an embodiment, the voice recognition module 263 of the processor 260 extracts a vector of voice features from information about the received user voice, and compares the extracted vector with the acoustic model of the database 251 or the server 30, thereby performing the voice recognition.

The processor 260 performs operations to process the user voice based on the foregoing voice recognition, and output the process result.

For example, as shown in FIG. 8, when the user voice is related to a request for searching for local restaurants, the processor 260 may perform searching through the communicator 240.

The processor 260 controls the display 230 to display an image corresponding to the process result (i.e. a searching result) in the operation 806 (807). For example, the processor 260 may, as shown in FIG. 8, control the display 230 to display a UI 501 showing the result of searching the local restaurants.

The processor 260 may control the communicator 240 to output a signal corresponding to the process result (i.e. the searching result) in the operation 806 to the electronic apparatus 10 (808). Here, the output signal may correspond to the process result received in the electronic apparatus 10 in the operation 607 according to the embodiment of FIG. 11 or the operation 708 according to the embodiment of FIG. 13.

The processor 160 of the electronic apparatus 10 may receive a signal corresponding to the process result as described above, and output a sound based on the received signal through the speaker 110. Therefore, the result of processing the user voice in the operation 807 may be not only displayed on the display apparatus 20 but also output as an audio feedback through the speaker 110.

According to the fourth embodiment of the disclosure as described above, when the display apparatus 20 is switched over from the turned-off state to the turned-on state, the display apparatus 20 may automatically perform connection settings according to whether it is connected for communication with the external apparatus, i.e. the electronic apparatus 10. Further, the display apparatus 20 receives the information about the user voice from the connected electronic apparatus 10, so that the user voice input to the electronic apparatus 10 can be processed in the display apparatus 20. Therefore, with regard to a user input for which a visual feedback is efficient, a process result is provided as an image through the screen of the display apparatus 20, thereby improving a user's accessibility to the process result, and more easily obtaining additional information as necessary.

FIG. 16 conceptually illustrates operation between an electronic apparatus and a display apparatus according to a fifth embodiment of the disclosure, FIG. 17 is a flowchart showing a method of controlling the electronic apparatus according to the fifth embodiment of the disclosure, FIG. 18 is a flowchart showing a method of controlling the display apparatus according to the fifth embodiment of the disclosure, FIG. 19 illustrates a user interface (UI) displayed on the display apparatus according to the fifth embodiment of the disclosure, and FIGS. 20 and 21 illustrate UIs displayed on the display apparatus according to the fifth embodiment of the disclosure.

According to the fifth embodiment of the disclosure, the electronic apparatus 10 monitors an operation for processing a voice received through the microphone 120.

The electronic apparatus 10 may be embodied to transmit a turning-on request to the external apparatus, i.e. the display apparatus 20 as shown in FIG. 16 based on occurrence of an error. In response to the turning-on request from the electronic apparatus 10, the display apparatus 20 may be switched over from the turned-off state to the turned-on state.

Here, the electronic apparatus 10 may identify the power state of the display apparatus 20, i.e. whether the display apparatus 20 is in the turned-on state or the turned-off state. When it is identified that the display apparatus 20 is in the turned-off state, the electronic apparatus 10 may output a guide sound for turning on the display apparatus 20 through the speaker 110. The guide sound may further include a message for informing that an error occurs in the electronic apparatus 10.

Further, when it is identified that the error occurs in the electronic apparatus 10, information about the error may be transmitted to the display apparatus 20 as shown in FIG. 16. The display apparatus 20 may perform an operation for correcting an error, based on the received information about the error from the electronic apparatus 10.

Specifically, as shown in FIG. 17, the electronic apparatus 10 may perform monitoring an operation for applying a voice process to a user voice received in the microphone 120 (901). Here, the monitoring is to identify whether an error occurs in the voice process for operating the electronic apparatus 10 as the AI speaker, and may for example include identifying whether an error occurs in user login, network connection, music or the like service settings, device settings, etc., in which there are no limits to the kinds of errors.

According to an embodiment, the monitoring in the operation 901 may be performed in response to occurrence of a preset event such as an input of a user, a signal input through the communicator 140, etc. or may be periodically performed at predetermined time intervals.

Based on the monitoring in the operation 901, the processor 160 may identify that an error occurs in processing the voice (902). Here, the processor 160 may further identify the kinds of occurred error, for example, an error in user login, an error in service settings, etc.

In the operation 901, when it is identified that the error occurs in processing the voice, the processor 160 may identify whether the display apparatus 20 is in the turned-off state or the turned-on state through the communicator 140 (903). Here, the processor 160 may transmit a preset signal to the display apparatus 20 through the communicator 140, and identify the power state of the display apparatus 20, i.e. whether the display apparatus 20 is the turned-on state or the turned-off state according to whether a response signal to the preset signal is received from the display apparatus 20.

According to an embodiment, the processor 160 may output a guide sound for guiding a user to turn on the display apparatus 20 through the speaker 110 based on the identification in the operation 903 that the display apparatus 20 is in the turned-off state (904). According to the disclosure, there are no limits to the guide sound to be output, and the guide sound may for example include content for guiding a user to press a specific button of the electronic apparatus 10 so that a turning-on request can be transmitted to the display apparatus 20, or content for guiding a user to turn on the display apparatus 20.

According to another embodiment, the operation 904 of outputting the guide sound may be omitted in the electronic apparatus 10.

When it is identified in the operation 903 that the display apparatus 20 is in the turned-off state, the processor 160 may control the communicator 140 to transmit a request signal for turning on the display apparatus 20 to the display apparatus 20 (905).

According to an embodiment, when a user presses the specific button in response to the output of the guide sound for the press of the corresponding button in the operation 904, the processor 160 may for example transmit a request signal for turning on the display apparatus 20 through the communicator 140.

According to another embodiment, when it is identified that the display apparatus 20 is in the turned-off state, the processor 160 may directly transmit the request signal for turning on the display apparatus 20 through the communicator 140 without the output of the guide sound in the operation 904 or a user's control. The guide sound for guiding a user to turn on the display apparatus 20 may be output through the speaker 110 (904). According to the disclosure, there are no limits to the guide sound to be output, and the guide sound may for example include content for guiding a user to press a specific button of the electronic apparatus 10 so that a turning-on request can be transmitted to the display apparatus 20, or content for guiding a user to turn on the display apparatus 20.

The turning-on request signal in the operation 905 is received in the display apparatus 20, so that the display apparatus 20 can be switched over from the turned-off state to the turned-on state in response to the reception. The processor 260 of the display apparatus 20 may control the communicator 250 to transmit a signal for informing that the display apparatus 20 is turned on to the electronic apparatus 10, and therefore a feedback signal to the turning-on request is transmitted to the electronic apparatus 10.

When it is identified in the operation 903 that the display apparatus 20 is in the turned-on state, the processor 160 may control the communicator 140 to transmit information about an error identified in the operation 902 to the display apparatus (906).

According to an embodiment, the processor 160 may automatically transmit the information about the error to the display apparatus 20 through the communicator 140 in response to the display apparatus 20 being turned on.

According to another embodiment, when it is identified in the operation 903 that the display apparatus 20 is in the turned-on state, the processor 160 may output a guide sound for correcting the error through the speaker 110 (904). According to the disclosure, there are no limits to the guide sound to be output, and the guide sound may for example include content for guiding a user to press a specific button of the electronic apparatus 10 to correct the error.

When a user presses the corresponding button in response to the guide sound, the processor 160 may transmit information about the identified error to the display apparatus through the communicator 140.

The display apparatus 20 receives the information about the error from the electronic apparatus 10, and perform an operation for correcting the error in the electronic apparatus 10 based on the received information. Detailed operations for correcting the error, which are carried out in the display apparatus 20 will be described in detail with reference to FIG. 18.

The processor 160 may receive a signal for informing whether the error is corrected from the display apparatus 20 through the communicator 140 (907).

Here, the display apparatus 20 performs the operation for correcting the error based on the information transmitted in the operation 906, and feeds the signal for informing whether the error is corrected or not back to the electronic apparatus 10 as a result of the operation, in which the corresponding signal is received in the electronic apparatus 10 through the communicator 140.

Based on the signal received from the display apparatus 20 in the operation 907, the processor 160 of the electronic apparatus 10 may output a sound for informing the corrected error through the speaker 110 (908). Therefore, a result from correcting the error may be not only displayed on the display apparatus 20 but also output as a sound corresponding to an audio feedback based on the process result through the speaker 110.

Meanwhile, as shown in FIG. 18, the display apparatus 20 may be switched over from the turned-off state to the turned-on state (1001).

Here, the turned-off state refers to a kind of soft turned-off state in which the display apparatus 20 operates in the standby mode of receiving the standby power. As the first processor 261 of the turned-off state is woken up by the second processor 262, the display apparatus 20 is switched over to the turned-on state, in other words, the normal mode.

In the operation 1001, the display apparatus 20 is turned on based on, for example, the turning-on request transmitted from the electronic apparatus 10 to the display apparatus 20 in the operation 905 of FIG. 17.

The display apparatus 20 may receive information about the error in processing the voice from the electronic apparatus 10 through the communicator 240 (1002). The information about the error received in the operation 1002 may correspond to the information transmitted from the electronic apparatus 10 to the display apparatus 20 in the operation 906 of FIG. 17.

The processor 260 of the display apparatus 20 may perform an operation for correcting the error, based on the information received in the operation 1001 (1003). Here, the processor 260 may automatically perform the operation for correcting the error, based on identification that the display apparatus 20 is tuned on and the information about the error is received.

According to an embodiment, the processor 260 may correct an error in the electronic apparatus 10, based on the setting information about the display apparatus 20. For example, when a login error occurs due to a user account in the electronic apparatus 10, the processor 260 transmits information about the user account of the display apparatus 20 to the electronic apparatus 10, thereby allowing a user to log in to the electronic apparatus 10 with the transmitted information about the user account. Like this, the setting information (or setting values) of both the apparatuses 10 and 20 is paired, and it is thus easier to automatically correct various errors that may occur in the electronic apparatus 10.

According to another embodiment, for example, when an error occurs in logging in to the electronic apparatus 10 with a user account, the processor 260 may control the display 230 to display a screen including menu items for setting a user account. When a user sets the user account along a guide on the displayed screen, data of the setting result is transmitted to the electronic apparatus 10, thereby correcting the error in user login.

According to still another embodiment, the processor 260 may control the display 230 to display a UI about occurrence of an error, and performs an operation for correcting the error based on a user's selection on the displayed UI.

For example, as shown in FIG. 19, the processor 260 informs a user that an error occurs in the electronic apparatus 10, i.e. the AI speaker, and controls the display 230 to display at least one UI 1101, 1102 or 1103 for allowing the user to select whether to correct an error. When the user selects the item 1102 of “YES” among the displayed UIs, the processor 260 performs the corresponding operation for correcting the error.

Alternatively, the processor 260 may, as shown in FIG. 20, inform a user that an error occurs in the electronic apparatus 10, i.e. the AI speaker, and controls the display 230 to display a UI 1104 including a message for guiding a user's control for the correction.

According to the disclosure, the displayed UI about the occurrence of the error is not limited to that shown in the drawings. When a user makes selection for the correction of the error in response to the UI shown in FIG. 19 or 20, the error may be corrected automatically or based on user settings in the same manner as those of the foregoing embodiments.

When the operation for correcting the error is performed in the operation 1003, the processor 260 may control the display 230 to display a UI for informing a user that the error will be corrected (1004).

For example, as shown in FIG. 21, the processor 260 may control the display 230 to display a UI 1105 for informing a user that the error in the electronic apparatus 10, i.e. the AI speaker is corrected and the electronic apparatus 10 is back in working order.

When the operation for correcting the error is performed in the operation 1003, the processor 260 may control the communicator 240 to output a signal for informing the error correction to the electronic apparatus 10 (1005).

The processor 160 of the electronic apparatus 10 may receive the signal from the display apparatus 20, and output a sound based on the signal, i.e. a sound for informing the error correction through the speaker 110. Therefore, the error correction in the operation 1003 is not only displayed on the display apparatus 20 but also output as an audio feedback through the speaker 110.

According to the fifth embodiment of the disclosure, when an error occurs in processing a voice in the electronic apparatus 10, information about the error is transmitted to the display apparatus 20, and thus the error is corrected using the display apparatus 20. Therefore, a visual feedback on the correction of the error is provided through the screen of the display apparatus 20, and the automatic error correction is more convenient for a user.

FIG. 22 conceptually illustrates operation between an electronic apparatus and a display apparatus according to a sixth embodiment of the disclosure, and FIG. 23 is a flowchart showing a method of controlling the electronic apparatus according to the sixth embodiment of the disclosure.

The electronic apparatus 10 according to the sixth embodiment of the disclosure may further include an infrared (IR) emitter capable of outputting an IR signal having a predetermined frequency band as compared with the electronic apparatus according to the embodiment shown in FIG. 3, and the display apparatus 20 according to the sixth embodiment may further include an IR receiver capable of receiving the IR signal as compared with the embodiment shown in FIG. 4. In other words, the electronic apparatus 10 can emit an IR signal, and the display apparatus 20 can receive the IR signal.

According to the sixth embodiment, the electronic apparatus 10 may, as shown in FIG. 22, transmit an IR signal for a connection request from the electronic apparatus 10 to the display apparatus 20, so that both the apparatuses 10 and 20 can be connected based on the IR signal. Here, the electronic apparatus 10 and the display apparatus 20 may be connected to each other based on Wi-Fi, Bluetooth and the like wireless communication.

According to the sixth embodiment, the electronic apparatus 10 for example emits the IR signal when turned on by power supplied for the first time. In other words, when the electronic apparatus 10 is supplied with power as installed for the first time, the electronic apparatus 10 and the display apparatus 20 may be automatically paired based on the IR signal.

The electronic apparatus 10 and the display apparatus 20 connected by the wireless communication exchange, i.e. transmit and receive account information including user information with each other, so that the account information between both the apparatuses 10 and 20 can be synchronized with each other in real time as shown in FIG. 22.

Specifically, as shown in FIG. 23, the electronic apparatus 10 may be turned on, in other words, switched over from the turned-off state to the turned-on state (1201). Here, the electronic apparatus 10 may be turned on by power supplied for the first time.

When the electronic apparatus 10 is turned on in the operation 1201, the processor 160 outputs the IR signal for requesting the connection (1202).

The IR signal output in the operation 1202 may be received in the display apparatus 20. Here, the IR signal is a short-range wireless signal having directivity, and is therefore unlikely received in other apparatuses than the display apparatus 20, for example, a television or the like of a neighboring house.

The IR signal output in the operation 1202 may include identification information for connection with the display apparatus 20. The identification information may for example include a Bluetooth device address, a MAC address, etc. and the IR signal may include the identification information corresponding to the first communicator 140.

Based on the IR signal transmitted in the operation 1202, the electronic apparatus 10 and the display apparatus 20 may be connected (1203).

According to an embodiment, the processor 260 of the display apparatus 20 receiving the IR signal may establish communication by trying connecting with the electronic apparatus 10 based on the identification information included in the received IR signal. As the communication is successfully established, the electronic apparatus 10 and the display apparatus 20 are connected to communicate with each other.

The electronic apparatus 10 and the display apparatus 20 connected to each other in the operation 1203 may synchronize with each other with respect to synchronize with account information (1204). Here, the account information may include user information for login, for example, identification (ID) and a password, etc., and the electronic apparatus 10 and the display apparatus 20 may exchange, i.e. transmit and receive the account information including the user information with each other, so that both the apparatuses 10 and 20 can synchronize with each other with respect to the account information.

Therefore, the electronic apparatus 10 and the display apparatus 20 may be logged in with the same account, and service histories used with the corresponding account, for example, searching histories based on user voices, a list of frequently played music, etc. may be collectively managed by the external server 30.

Further, when there is a change in the account information, the electronic apparatus 10 and the display apparatus 20 may synchronize with each other reflecting the change in real time. Here, the changed account information may be transmitted to the server 30 in real time, so that the changes can be applied to not only the electronic apparatus 10 and the display apparatus 20 but also other devices such as a smartphone, etc. usable with the corresponding account.

According to the sixth embodiment of the disclosure, the electronic apparatus 10 outputs the IR signal when supplied with power to automatically connect with the display apparatus 20, and is therefore inconvenient for a user who is not used to using electronic devices because the user does not need to separately do communication settings. Further, the electronic apparatus 10 and the display apparatus 20 which are connected synchronize with each other with respect to the account information, so that a user can get services reflecting the up-to-date data under the same environments in all apparatuses.

As described above, according to an electronic apparatus, a display apparatus, and a method of controlling the same, the electronic apparatus capable of receiving and processing a user voice autonomously processes the user voice or allows the display apparatus to selectively process the user voice, and provides process results in accordance with on/off states of the display apparatus, thereby extending functions and services.

Further, according to an electronic apparatus, a display apparatus, and a method of controlling the same, the electronic apparatus autonomously processes a received user voice or allows the display apparatus to selectively process the user voice, and provides process results in accordance with service/content types provided by voice processes, thereby receiving more efficiently the service/content through a screen when visual feedback is needed.

Further, according to an electronic apparatus, a display apparatus, and a method of controlling the same, the electronic apparatus provides information about an error in processing a user voice to the display apparatus, so that the error can be corrected through the display apparatus.
